The uniqueness of individuals is a striking scientific fact, but it is just one of those facts that can hardly be done justiceto in an obituary notice. In writing this brief memoir of my departed friend, Ernest Blacker, I am regretfully conscious of this shortcoming. It may, however, be stated that his was a cheery, neat, alert and debonair personality, rich in human sympathies and sociabilitie...

Individuals of gregarious species that initiate collective movement require mechanisms of cohesion in order to maintain advantages of group living. One fundamental question in the study of collective movement is what individual rules are employed when making movement decisions. Previous studies have revealed that group movements often depend on social interactions among individual members and s...

Regular physiological observations were made on the members of the NorwegianBritish-Swedish Expedition 1949-52 (NBSX) to the Antarctic (Giaever, 1954) during their 2-year stay in the Antarctic as well as before they left for the south and after they returned home. The NBSX landed in the Antarctic in February 1950 and departed in January 1952. Accounts of the climate and working conditions on th...

in this paper a robust road departure avoidance system based on a closed-loop driver decision estimator (dde) is presented. the main idea is that of incorporating the driver intent in the control of the vehicle. the driver decision estimator computes the vehicle look ahead lateral position based on the driver input and uses this position to establish the risk of road departure. to induce a risk...

In this paper, we proposed an online gaming traffic generator reflecting user behavior patterns. We analyzed the packet size and inter departure time distributions of a popular FPS game (Left4Dead) and MMORPG (World of Warcraft) for regenerating gaming traffic. The proposed traffic generator generates an inter departure time and gaming packet based on analytical model of the gamer behaviors, th...

This paper presents a departure-time user equilibrium model that explicitly considers the most important determinants of congestion behavior in cities during the morning commute: different commuter origins, merge interactions and queue spillovers. The proposed model combines three previous works: the departure-time equilibrium theory in Vickrey (1969), the traffic flow model of Newell (1993) an...

Numerous models of travel timing have been calibrated in the literature. Some treat time as a discrete variable using familiar discrete choice methods, while others have treated time in a continuous fashion. Both approaches offer distinct advantages. Here, a continuous logit model of work tour departure time choice is estimated, which offers the advantage of continuous-time response using a ran...
